1. To calculate a 15% tip on a $24.00 bill a customer adds$2.40 and half of $2.40 or$1.20 to get $3.60. Is his procedure valid? Why or why not? 2. -------------------------------------------------------------------------------- Is it always best to convert from fraction notation to percent notation by first finding decicimal notation?

\$2.40 is 10%

Half of 2.40 is half of 10%, which is 5%

So 10% + 5% = 15%

So his procedure is valid.
